[News] Samsung Refutes Rumors Regarding 3nm Wafer Defects as Groundless

Rumors have been circulating regarding Samsung’s 3nm yield recently. The latest market speculation on June 25^th alleged that Samsung’s foundry plant encountered a defect impacting 2,500 lots in the 3nm second-generation process, reportedly leading to a loss of 1 trillion won (USD 720 million), according to the latest report by the Chosun Daily.

On June 26^th, the semiconductor giant denied the rumors of a major defect in the production of semiconductor wafers at its foundry division in South Korea. Market speculations emerged earlier, suggesting that all the affected wafers, which equal to 2,500 lots, had to be discarded, the report noted. The volume corresponds to roughly 65,000 12-inch equivalent wafers per month.

According to the Chosun Daily, Samsung claimed that the rumor of “discarding them (the affected wafers) all” circulating in the stock market are unfounded. The current status of the products from the affected production line is still under evaluation, the report said.

Citing industry insiders familiar with the matter, the Chosun Daily noted that the reported figures might be exaggerated, pointing out that Samsung’s 3nm production capacity is less than 60,000 wafers per month. Furthermore, there are numerous inspection processes in place throughout the production line, indicating that such a large-scale defect may be improbable.
